The surface of a sample of the imported chicken wings tested positive for the virus, the city of Shenzhen said in a statement on WeChat.
The city’s Epidemic Prevention and Control Office organised nucleic acid testing for everyone who may have been exposed to the products, authorities said, adding that the results came back negative.
China, in recent months, started screening all meat and seafood containers coming into major ports.
Screening efforts intensified after a coronavirus outbreak in Beijing in June was linked to the city’s Xinfadi wholesale food market.
The first coronavirus outbreak in December was linked to the Huanan seafood market in the central city of Wuhan.
